Ramshot competition 180 bbi

Recommended Posts

I was really excited to try this powder...

I know 3 people using it with excellent results.

Unfortunately I'm not one of them :(

I have 20lbs of this stuff not sure what to do with it...

Ideally I like to get it to work, at least for practice...

Being that I'm loosing velocity when pushing passed 4.4 I'm wondering if maybe i need to drop the charge instead of increasing it? Maybe I'm at some strange place in the pressure curve?

I didn't see any signs of over pressure on the cases it...

If you have a 9mm you want to run.....147gr projectile with 3.1 gr on Competition is fantastic. ( and make minor with 10% to spare)
I have not tried to load any for a .40 with Competition but ZIP has worked well.

I'm at 4.6gr @ 1.180 out of a STI Edge for major PF. I haven't tried magnum primers though.

Is this for competition or static stuff?

Yeah for sure Uspsa...

I was told 4.6/4.7 would be the number...

I hesitate to think it's the magnum primers as I've been using them for years and they usually only add like 50fps...

I do have some small pistol primers so i might roll a small batch at 4.6 and 4.7 to see where it's at...

It's just really odd that my velocity actually went down the more powder I put in it...

Maybe you mixed up which rounds were which.

Not possible... They were put in baggies and labeled as they came of the press...

I think I have a bad lot, or the magnum primers are running a mock

I ran 3.7gr 200gr bbi 1.155 oal ts40 over my chrono and was at 176pf.

Working up 3.6 and 3.5 to see what happens over the chrono.

My main load is wst 4.0gr to make major.

Yeah I think this batch is way hotter than I anticipated...

Tomorrow I'm running 4.0 to 4.7 just to try and get a better idea of what the pressure curve is doing...

I use 4.9 of the stuff loaded at 1.180 fir a PF of 170-175 depending on the chrono. Try bumping it up a little more and see if they get a little more consistent.

I've loaded 4.0 to 4.7 just to get a better idea of the pressure curve...

If it all goes well I will try 4.8 and 4.9...

I'm also going to do some 4.6 and 4.7 with small primers...

Following this thread as I have 4# to try. Was considering 4.5 gr with 180 gr Bayou at 1.2" out of a 5" 2011. Based on the info here that should be in the ball park for major.

For those that haven't, can you share the COAL as well? I can make some educated guesses based on pistol if given, but load info is much more useful when you have the COAL.

Ok had a better second day of chrono..

The major changes were new battery on the chrono, cloudy day...

And the chrono and ammo were not as hot from being under direct Texas sun light...

4.7 seems to be it for me...

Dave,

What is your OAL for the 147gn 9mm?

Thanks.

Any update on this combo or 180 coated lead and RSC?

4.7 made 171 pf for me...

i use magnum primers, but standard primers seem to shoot hotter, and more consistent.

This powder is a bit sensitive to OAL

so make sure your dies are tight.

my oal is 1.175 to 1.18
